rApplication filed April 1, 1915. Serial N o.18,608.

MCQUEEN, a citizen of the United States, Y

residing at New York, in the county of New York and State of New York, have'invented certain new and useful Improvements in Casement-Lifts and Hinges, of which the following is a specification.

This invention relates to window lifts and hinges and particularly to a lift and hinge which is especially .designed for use in connection with a window structure wherein the sash or easement is designed to be lifted in a vertical direction immediately prior to the time of swinging the easement in a horizontal direction for the purpose of opening the same, or at the time of lowering the easement and seating the same behind the sill stop of thevwindow frame on returning the easement to its full closed position.

The principal purpose in view in devising the above mentioned device may be stated to be that of simplicity of construction; durability, general compactness and elliciency; a device which will bepositive in action, and one by which the easement with which it is associated may be expeditiously operated.

In casements of the horizontal swinging and vertically ysliding type, it is customary to provide the sill with a horizontal stopover which the easement is designed to swing after. it is elevated, and behind which the easement is adapted to be seated when fully closed and in order to effect a perfect operation of the easement the combined hinge and lift is provided with means which will per mit of such vertical movement of the casement as is necessary'to enable the same to swing freely and not frictionally or unduly impinge against the frame or otherwise engage with the latter in any way which might hinder its freedom of movement.

The invention has for a further object, the provision of a hinge consisting of a pair of leaves, one of which being free to swing from the other lbut fixed against sliding movement thereon and terminating in a branch with which is associated a lifting mechanism mounted within a housing which has iiXed connection with the easement vand which housing is so peculiarly formed that it will combine or coperate with the adjacent hinge leaf to furnish therewith, a substantial brace whose function is that of hold-s ing-the easement against undue sagging'or assuming any other detrimental position 1n the frame that would interfere with thev closing or opening of the easement. I further aim to connect the housing to one of the hinge leaves so that it will appear to be a continuation thereof and to also construct said housing whereby it may be readily mounted in a mortise formed in the inner .face of the vertical stile of the easement and 1n such a manner that the mortise will be concealed by one plate thereof of said housing.V In this way the housing and hinge leaves will combine to represent a complete hinge; adding materially to the attractive character of the device and to further eX- pedite the operation of applying the device to the easement and frame.

In the drawings Figure 1 is an elevation of a portionof a frame and its easement. illustrating the application of the combined thereto and showing the normal position.

Fig. 2 is a similar view showing the casement elevated.

The easement A is free to move in a vertical direction in the frame B and also to swing horizontally.v When the easement is closed as in Fig. l its basebar Crests upon the sill D and behind lthe stop strip E which rises therefrom. These parts may be of the usual or any other well known form and they are therefore only specifically referred to in order that the inventionY and its purpose can be fully appreciated or understood.

The Casement herein shown opens from the left and on the left side thereof is mounted a housing l consisting of an outer mortise Vconcealing plate2 and an inner plate 3.

at 9 and then angularly as at 10. The exy tension 10 is rabbeted in the adjacentJ vertical edge'of the easement and secured therein by fastening screws 11. The surface 12 i5 of the extension 9 is disposed at right angles to the position of the adjacent vertical edge 13 of the plate 2. The surface 12 and the mentioned edge 13 of the housing plates freely bear respectively against mating surfaces 14 and 15 of the free hinge leaf 16. The housing is secured to the Casement by means of screws 17. Through this construction the housing is adapted to nicely lit in a single mortise formed in the inner face of the vertical stile of the easement, as illustrated in Fig. 3, and it will be made to appear as a part of a hinge structure to be referred to hereinafter.

The hinge 13 consistsvof the mentioned free leaf 16 and a second leaf 19, the latter having xed connection, with the frame B as at 20 and it carries three knuckles 21, 22, and 23 between which, the two knuckles 24 and 25 of the leaf 16 are interposed. Both of these leaves are normally disposed within the vertical plane of the stile A of the casement so that the tongue A of the easement can freely come in contact with the rabbeted walls B of the frame B, as shown in Fig. 3. rThrough all of these knuckles a pintle 26 is passed having fixed caps 27-27 as shown. This construction is such that one leaf is mounted to freely swing from the other, yet it is properly held against sliding thereon. 4.5 rThe described number of knuckles upon the respective hinge leaves have been found to give splendid results but it is desired to mention that such arrangement is not wholly essential, yet preferred for a purpose to be hereinafter referred to.

The leaf 16 has an integral saddle 23 formed with branch arms 29-29 which forms a part of the lifting mechanism, whereby the housing can be moved in a vertical direction on the hinge. These arms 29-29 are each provided on its inner face with a hardened surface 30, preferably a steel plate and operating thereover is an eccentric 31 which forms the other part of the lifting mechanism. This eccentric is interposed between the plates 2 and 3 of the housing and it is provided with a substantially U-shaped recess 32 which receives a correspondingly formed boss 33 on a revolv- G5 ing stud 34 respectively mounted to revolve rangement.

in the plates 2 and 3. A screw 34 extends through the boss 33 and it enters the eccentric as at 35 and in this manner the latter is securely held in place upon the stud. The distance between the arms 29-29 is approxi- 70 mately equal to the diameter of the eccentric and as a consequence thereof it results that the housing will be moved in a vertical direction when the eccentric is rotated. The stud carries an operating handle 36 which 75 is exposed from the front plate 2 of the housing and when in the position shown in Fig. 1 the eccentric is freely interposed between the arms 29-29 and the bar C of the Casement seated behind the stop strip l). 50 l/Vhen the handle is in the position shown in Fig. 2 the eccentric is bearing against the lower arm 29 and the easement elevated above the stop strip, as will be understood. By simply turning the handle 36 it follows that movements in an upward or downward direction will be imparted to the easement.

t is desired that notice be taken of the position of the anges 6 and 7 with relation to the axis of the eccentric. This relation of the described parts is nicely shown in Fig. 4 and when the handle 36 is down the eccentric bears against the surface 37 of the iiange 6. When the handle'is up as shown in Fig.

2 the eccentric bears against the stop surg5 face 38 of the flange 7. Through this construction, the handle can only be moved, for a limited distance with relation to the adjacent side bar of the frame B and the hand of the operator is held against suddenly coming in contact with the casing, and principally and most important, through said arrangement, the easement may be accurately adjusted in a vertical direction as will be seen, and when it contacts with said surface 10.5 38, the Casement is positively free to pass over the strip D.

The plate 3 has a vertical guide slot 39 formed therein and extending therein is a lug 40 on one side of the hinge leaf 16. This 11o lug 40 and slot 39 combine with the coacting surfaces 9 and 14 and 13 and 15 to brace the hinge elements in a very substantial manner and the easement is properly held against undue sagging during its swinging movement and accuracy of operation of the casement follows or is resultant from such ar- The lug 40 further serves to hold the housing operatively connected with the hinge.

The specic arrangement of the hinge knuckles 21, 22, 23, 24 and 25, when taken with the surfaces 9 and 14 and 13 and 15 is desired as it is found that the strain upon the structure is evenly distributed and the 125 several parts are satisfactorily held against breaking from one another under most trying conditions.

The mortise concealing plate 2 of the housing 1 has a length approximately equal 13o to that 0f the hinge and from the showing in Fig. l, the housing and the hinge will be made to appear as a single hinge structure.

Having described the invention, what is claimed is:

1. A easement lift comprising a housing mounted in a mortise in the inner side of the vertical stile of the easement and including inner and outer plates, the outer plate having a continuous vertical slot, a hinge having one leaf secured to the frame and a second leaf extended between said plates'and free to slide in a vertical direction and provided with spaced arms, a lug extending between said arms land freely movable in said slot, and means co-acting with the arms to slide the easement vertically.

2. A easement lift comprising a housing mortised in the Casement, and having a vertical slot in one of its walls, a hinge having one leaf secured to the frame and having its other leaf extending into the housing and adapted to permit the latter to slide thereon, a pair of arms carried by said other leaf, a continuous lug connecting the arms with each other and freely passing into the slot, the length of the slot exceeding the length of the lug, a pair of knuckles formed on said other leaf, the frame leaf having an unequal number of knuckles thereon, a pin passing through the first and second named knuckles and lifting mechanism moving the housing on said other leaf, said leaf having free contact with the housing and coperating with said slot and lug to form a guide for the housing.

3. A easement lift and hinge including parallel leaves, one of said leaves being adapted for connection vwith the frame, two plates adapted to be secured to the easement, one of said plates being mounted in a mortise formed in the inner face'of the vertical stile of the casement, the other plate being extended over the inner face of the casement to conceal the mortise and being coextensive in length with the next adjacent' leaf of the hinge and having a continuous edge portion arranged in sliding contact therewith, to form a brace in the full length thereof, means on said next adjacent leaf interposed between said plates, and lifting mechanism permanently carried by said plates and co-acting with said means.

In testimony whereof I aflix my signature in presence of two witnesses.
